All Out is a pay-per-view (PPV) held annually around Labor Day by All Elite Wrestling (AEW) since 2019. It is one of AEW's "Big Four" PPVs, which includes Double or Nothing, Full Gear, and Revolution, their four biggest shows produced quarterly.[2] The 2021 event will be the third event in the All Out chronology and will be held on September 5 in the Chicago suburb of Hoffman Estates, Illinois, returning the event to the Now Arena (formerly Sears Centre Arena), which is where the inaugural All Out was held.[3][4] It will be AEW's first pay-per-view held outside of Daily's Place in Jacksonville, Florida since the start of the COVID-19 pandemic in March 2020, following AEW's resumption of live touring in July 2021.[5] Presale tickets were available July 8 before they went on sale on July 9 to the general public and quickly sold out.[6]
